It's only just started to make this noise today, I've had this printer for a few years now and have only had minor problems where I needed to replace the hot end and nozzle.. I think it's the belt on the bottom that's making the scratchy noise but there isn't anything underneath it or anything jamming it. There was a loose bit of fillerment from my previous print underneath the hotbed that I removed before starting this new print. I'm just at a loss here. Do I need to replace the belt?

Note: The noise isn't constant, it comes and goes but it's regular enough to concern me
